In 1968, the only series that has SPs is the 6th series (458 to 533, plus checklist 6 again (454)). I know there are a plethora of these cards available, but I still plan an attempt to reconstruct the two slits so that we know what the short prints are. So, I am looking for images of either miscuts, wrong backs, or uncut material from that series.
So far, all I have are images of 485 showing edge of slit, 475, 519, & 520 showing edge of card above each, a diamond cut 480, and a miscut of 490 showing that 533 is below it. Any help would be appreciated.
